Question

Which tissue of the leaf contains chloroplasts?

Answer 1

Hint: Chloroplasts are the cell organelle present in plant cells and algal cells that perform photosynthesis, which is the process of converting light energy into energy that can be stored in the form of sugar and other organic molecules that the plant or alga can use as food. There are two stages to photosynthesis. The light-dependent reactions take place in the first stage.

Complete answer:
A continuous vascular system connects the leaves to the rest of the plant, allowing for the free exchange of nutrients, water, and photosynthesis end products (particularly oxygen and carbohydrates) to the plant's various parts. Leaves and stem tissues are both initiated in the apical bud (growing tip of a stem).
The leaves are the primary photosynthetic organs of plants, acting as key sites for the conversion of light energy into chemical energy. A leaf, like the other organs of a plant, is made up of three basic tissue systems: dermal, vascular, and ground tissue. These three motifs are present throughout the plant, but their properties vary significantly depending upon the organ type in which they are located.
Chloroplasts are found in the leaf's palisade layer. It can be found near the top of the leaf. The palisade layer is one of the leaf's middle layers. You would start from the upper surface of the leaf and work your way down through the leaf cuticle, which is the waxy coating that keeps the leaf from losing too much moisture. The upper epidermis is the single-celled, clear layer that allows the sun to shine through to the layers below.
Palisade cells are found in the mesophyll of a leaf and their primary function is light absorption for photosynthesis to occur. The palisade mesophyll is made up of chloroplasts that contain chlorophyll and absorb light energy.

Thus, the Palisade tissue of the leaf contains chloroplasts.

Note:
Palisade cells are typically 30-40 microns wide. In comparison to a nerve cell, which can be a meter long, a red blood cell (animal cell) is only 7 microns long, which is not too small.
