Plant Cell

Last week, my classmates I had a biology practicum. We observed parts of the plant cell. Then, I was thinking to share this plant cell to you, so I took several photos from the ocular lens.

Plant cell 100x
Plant cell 100x
Plant cell 40x

In the diagram of plant cell 40x, you can see an oval-like center. It is known as vesicular bundle. Vesicular bundle contain of xylem and floem. Xylem has a function to carry water and minerals from the ground to the cell. Floem has a function to distribute the product of photosynthesis to the whole part the plant.

The most upper part from the diagram is cuticle, which has a function to protect the cells inside.
Just below the cuticle, we have upper epidermis.
You also can see a green line, which is called as chloroplasts. It is function to absorb and trap the sunlight. Chloroplast is located in the mesophyll layer, palisade and spongy.
