The chloroplast of plants are most close in size to what?
The chloroplasts of plants are most closely in size to bacteria cells, specifically cyanobacteria. They are both relatively similar in size and share certain structural features, such as a double membrane.
What cell part do chloroplasts lie?
Chloroplasts live in plant and algal cells. Their main role in the ecosystem is to conduct photosynthesis by capturing the energy from the sunlight for storage.
What does the endosymbiotic theory purpose?
concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells. According to this theory, these organelles originated as separate prokaryotic organisms which were taken inside the cell as endosymbionts. Mitochondria developed from proteobacteria (in particular, Rickettsiales or close relatives) and chloroplasts from cyanobacteria. concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

What is some information about plant cells?
Plant cells are eukaryotic cells. They have a cell membrane and a cell wall. The cell wall is made up of cellulose, which is a polysaccharides made up of beta glucose. Plants often have a giant vacuole that store food, water, wastes and other dissolved minerals. Plants have chloroplasts which contain chlorophyll. Chloroplasts is the cite of photosynthesis in plants. Plant cells are autotrophs, meaning they produce their own food, unlike animal cells. Plants do not have centrioles for cell division, instead they have MTOC's or micro tubule organizing centers where the spindle fibers form when the cell starts to divide during prophase of mitosis or meiosis. Plants have xylem and phloem as part of their vascular tissues. Xylem transports water up the roots through capillary action, Phloem transports carbohydrates (sugars) to the cells. Plants regulate the exchange of Oxygen and CO2 through the guard cells in the stomata. The guard cells open and close when the cell needs Oxygen or needs to release carbon dioxide. These are some facts, but not all, on plant cells.
Where can you find chloroplast?
Chloroplasts are located in plant cells, suspended in the cytoplasm. If you look close enough at plant cells, you will see that they are not uniformly green, but the color, in fact, is consolidated into chloroplasts, which appear as small "green dots" in the cell. A plant cell can contain between 11 - 65 chloroplasts, which are each about 3 micrometers in diameter.

Is it true that guard cells of non desert plants often close during the daytime and open at night to conserve water?
The guard cells of non desert plants simply contract a bit but do not close. Desert plants close their guard cells.
What do cheek cells look like?
They look like animal cells which kind of look like small tiny blobs if you see them under a microscope with a very low objective. And of course if you see the cheek cells under a high objective, you will see the blobs but it will be in a close up. But it also depends on the cheek cells....

Why is the mesophyll an ideal site of photosynthesis in the leaf?
The mesophyll is the ideal site for photosynthesis in the leaf because it contains a high concentration of chloroplasts, where photosynthesis takes place. It also has a large surface area for light absorption and a network of air spaces that facilitate gas exchange for photosynthesis. Additionally, the mesophyll cells are positioned close to the leaf surface, allowing for efficient light penetration for photosynthesis.
Do all plants have guard cells?
No, not all plants have guard cells. Guard cells are specialized cells found in the epidermis of leaves and stems of plants, particularly in vascular plants, that control the opening and closing of stomata. Non-vascular plants like mosses and liverworts do not have true vascular tissue or stomata with guard cells.
What is the importance of guard cells?
If by guard cells you mean the ones located in plants, they open and close the stomata to control water loss :)
How many chloroplasts are there in a plant cell?
There is no exact number as it varies from cell to cell.
