    It must be, prokaryotes only have ribosomes as an organelle and will not have chloroplasts, whereas in eukaryotes only euglena have chloroplasts except for plants, but it belongs to animals and does not have a cell wall. So it must be plants.

    Yes, the important point of classification is to follow the definition, and then pay attention to the words (chlorophyll and chloroplast are not the same test points) To classify it simply, prokaryotes do not necessarily have chlorophyll eggs must have a cell wall Protozoe in protists have chlorophyll and cell wall The fungus kingdom does not have chlorophyll or chloroplasts, it has a cell wall of chitin The plant kingdom has chloroplasts and cell walls Learning a good classification of organisms focuses on the basic definition Oh References: Yourself I hope the above is helpful to you.

    Yes, because plants have cell walls and chloroplasts, like cyanobacteria are prokaryotes, there are no chloroplasts, only chlorophyll, so having chloroplasts and cell walls must be plants.

    It must be ah, plant cells have chloroplasts and cell walls, I hope mine will help you

    Because some prokaryotic cell algae also have cell walls and chloroplasts, but it does not belong to plants but to prokaryotes.

    Be. Prokaryotic organelles only have ribosomes, and the presence of chloroplasts means that they are eukaryotes, so they are plants.

    Not all, there are many microorganisms that have chloroplasts and cell walls such as plankton.

    Cells that have chloroplasts do not necessarily have a cell wall, for example Euglena is a single-celled organism that has chloroplasts within the cytoplasm of Euglena. The shape of chloroplasts (e.g., oval, macrodisc-disc-shaped, flake-like, band-like, stellate, etc.), size, number and structure (presence or absence of protein nucleus foci and parastarch sheath) are the taxonomic characteristics of Euglena genera and species.

    Chloroplasts are the most important and ubiquitous plastids within plant cells, and they are organelles that carry out photosynthesis. Chloroplasts use their chlorophyll to convert light energy into chemical energy and CO2 and water into sugar. Chloroplasts are the world's lowest-cost biofactories that create the most material wealth.

    It can be said that the energy required for almost all life activities is solar energy (light energy). Green plants are the main energy converters because they contain chloroplasts, which are organelles that complete energy conversion, which can use light energy to assimilate carbon dioxide and water, synthesize organic jujube matter that stores energy, and produce oxygen at the same time. Therefore, the photosynthesis of green plants is the fundamental source of the survival, reproduction and development of organisms on the earth.

    Chloroplasts may have originated from ancient cyanobacteria because of the chlorophyll found in cyanobacteria. Some ancient eukaryotes survived by devouring other organisms, and some of the cyanobacteria they swallowed were not digested and instead relied on the domestic waste of the devourers to make nutrients.

    The chloroplasts of higher plants are found in the cytoplasmic matrix. Chloroplasts are generally green, flat, fast-flowing, ellipsoidal or spherical, and their morphology and distribution can be observed with a high-powered optical microscope.

    Not all plant cells contain chloroplasts, chloroplasts are mainly found in mesophyll cells, and some young stem cells also have chloroplasts, but there are no chloroplasts in root cells and leaf epidermal cells, so all plant cells have chloroplast errors.

    Chloroplasts are the sites where plants photosynthesize. Chloroplasts contain chlorophyll, so most of the cells containing chloroplasts are green, and some fruits can be transformed into chromosomes during the ripening process, making the fruit appear in various colors.

    1.Not all plant cells have chloroplasts, plant root cells do not have chloroplasts, and there are no epidermal cells of leaves, this is because they do not have chloroplasts because they do not have photosynthesis.

    2.Chloroplasts are found in the epidermal cells of young stems, mesophyll cells and fruits, which belong to the site of plant photosynthesis, so for plant cells that do not see light, it does not contain chloroplasts.

    Chloroplast is a place for photosynthesis to make organic matter, and the chlorophyll in chloroplast can absorb light energy, convert light energy into chemical energy, and store it in the organic matter it produces Not all plant cells contain chloroplasts, such as the epidermal cells of onion scales and the cells of plant roots

    Therefore, the answer is: no, yes; For example, there are no chloroplasts in the epidermal cells of onion scale-sensitive leaves and in the cells of plant roots

    Not all plant cells contain chloroplasts. Chloroplasts are only found in some higher plants and some algae, and large single-celled prokaryotes like cyanobacteria do not have chloroplasts. Chloroplasts are a type of plastid and are energy converters peculiar to higher plants and some algae.

    Its double-layer membrane structure separates it from the cytoplasm and has a lamellar membrane containing chlorophyll, hence the name chloroplast.

    In higher plants, chloroplasts are like biconvex or planoconvex lenses, with a long diameter of 5-10um, a short diameter of 2-4um, and a thickness of 2-3um. The mesophyll cells of higher plants generally contain 50 200 chloroplasts, which can account for 40% of the cytoplasm, and the number of chloroplasts varies according to the cell type, ecological environment, and physiological state of the species. In algae, chloroplasts have various shapes, such as reticulated, banded, lobed and star-shaped, etc., and the volume is huge, up to 100um.

    Chloroplasts are composed of three parts: chloroplast outer cover, thylakoids, and matrix, and it is an organelle that contains chlorophyll for photosynthesis. Chloroplasts contain 3 different membranes: the outer membrane, the inner membrane, the thylakoid membrane, and 3 types of cavities that are separated from each other: the intermembranous space, the matrix, and the thylakoid lumen.

1. Maintain the shape of the cell, control the cell growth The cell wall increases the mechanical strength of the cell, and bears the turgoring pressure of the internal protoplasts due to the water absorption of vacuoles, so that the cell has a certain shape, which not only protects the protoplast, but also maintains the inherent morphology of organs and plants. In addition, the wall controls the growth of the cell because the premise for the cell to expand and elongate is for the cell wall to relax and irreversibly stretch. >>>More

Hello, green algae has a three-layer cell wall, and its most praised detoxification effect is also due to this. The middle and thickest cell wall, which binds toxins, is made up of cellulose-containing microfibers that form a tiny structure to which heavy metal molecules cling to the web. In addition, the German medical community found that the cell wall in the middle of the green algae contains a special substance sporopollein, which not only has the function of confirming poisons, but also has the characteristics of combining with various toxins without reversing, firmly grasping the toxins, excreting them from the body, and purifying the body. >>>More
