<span>The answer is C. This is because the discovery of
the cell and its organelles began with the discovery of the microscope in the
17th century. As powerful microscopes were developed over time, the
cell organelle become discover-able by different scientists. As other developments emerged, they enabled tagging of
elements, hence monitoring of biochemical pathways also became possible.</span>

The leaf as a photosynthetic organ includes the following cells which contains chloroplasts
--> the palisade mesophyll
--> the spongy mesophyll and
--> the stomatal guard cells
Although all the green parts of a plant can be involved in the photosynthetic activities (with the exception of the root hairs), the leafs are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the chloroplasts of these plant. Chloroplasts are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous chloroplasts and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain chloroplasts.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains chloroplasts which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains chloroplasts are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

Answer:
i dunno thats confusing and i cant see it sadly
Explanation:
The answer you chose is correct becAuse if both parents are heterozygous for a disease that is recessive there is a 25%chance of the offspring inheriting the trait.Ex:
R r
R (RR) (Rr)
r (Rr) (rr) rr is the only outcome that can inherit the disease.
