Chloroplasts

Ribosomes are present in chloroplasts and mitochondria because both organelles have their own DNA and protein synthesis machinery. They need ribosomes to translate the genetic information from their DNA into proteins that are essential for their proper functioning. Additionally, chloroplasts and mitochondria are believed to have originated from ancient bacteria that were engulfed by a host cell, and these bacteria-like organelles still retain some of the features of their bacterial ancestors, including the presence of ribosomes.

Animalia and Fungi are two kingdoms that do not have chloroplasts. While they have other organelles and structures that perform similar functions, such as mitochondria, they do not possess chloroplasts for photosynthesis like plants and some other organisms do.

If the interior of the thylakoids of isolated chloroplasts were made acidic and then transferred to a pH-8 solution, it is likely that the pH imbalance would trigger a process called proton motive force. This would lead to the movement of protons from the thylakoids to the surrounding solution to restore equilibrium. As a result, ATP synthesis would be inhibited, and the overall rate of photosynthesis would be affected.

Yes, chloroplasts are present in guard cells. Guard cells are specialized cells found in the epidermis of plant leaves and stems that regulate the opening and closing of stomata. Chloroplasts, which contain the green pigment chlorophyll, are responsible for photosynthesis and are necessary for the energy production needed for the opening and closing of stomata.

the photosystems

Chlorophyll is a green chemical inside chloroplasts. It carries out photosynthesis, which makes energy for a plant using sunlight. In fact, when you get a grass stain on your clothes, the green stuff is chlorophyll.

The Difference:

the major difference between chloroplast and mitochondria is that the latter contains thylakoid membrane and pigment molecules, whereas the mitochondria membranes contain respiratory enzymes not found in chloroplast membrane.

Similarities:

They both are the main powersource of the organism.(Mitochondria producing ATP through the krebs cycle and chloroplast uses photosynthesis to produce glucose.)

Hydra is an animal. Animals never have chloroplasts

Chloroplasts need sunlight for function. Root hairs do not get sun light

Dark reactions take place in the stroma of the plant cell.

Humans are heterotrophic and feed from other organisms. They do not carry out photosynthesis, which is the function of chloroplasts. Plants need chloroplasts as they are autotrophic (i.e. they produce their own food using sunlight).

Only plant cells have chloroplasts.

Carbon dioxide enters through small openings called stomata on the leaf surface, while water is absorbed by the roots and transported to the leaves through vascular tissue. Both carbon dioxide and water then diffuse into the chloroplasts in the leaf cells where photosynthesis occurs.

the function of chlorophyll pigments is trapping the sun's energy and using it for nutrients. this production is called photosynthesis. it also gives the plant the green colour that it carries when photosynthesis is in progress. usually you can start to see this production in spring when the sun comes out more often.

Chloroplasts are disc-shaped to provide a large surface area to absorb light. They are also located close to the surface of the leaf to capture maximum light, located near to veins for easy water diffusion and are small in size to enable them be packed in a small space.

Spirogyra is a type of green algae, named for the spiral arrangement of the chloroplasts. The arrangement of the chloroplasts are helical or spiral.

Because of the 69 inside of the cell lol

Chloroplasts are found in the cells of young stems and immature fruits, leaves are the real photosynthetic factories of the plant.

They don't have have chloroplasts because they are underground in the dark and cannot photosythsize

Plants use the red and blue light from the visible light spectrum; these are captured in the wavelengths between 440 and 660 nanometres. Green light is reflected, giving plants their green colour. Day length also plays an important factor in the effectiveness of photosynthesis.

Since red is the most abundant colour in visible light, then it could be referred to as the "most useful" since it is the one used most.

Bear in mind that photosynthesis is not the only process involving plants and light, since insect pollinated flowering plants (angiosperms) use bright colours to attract insects and other animals, in which case, light is required in many forms, not only visible, but some ultraviolet, since several insects see by means of ultraviolet light.

if they are plant cells

Chlorophyll is found within organelles within the cell called chloroplasts.

It is used as carbon source. It is used to make glucose
