Answer:
The correct answer is -
1. stomata - openings that are most frequently found on the underside of a leaf.
2. Palaside layer - the layer in the leaf that is the primary spot of photosynthesis.
3. spongy layer - the layer within the leaf that has many holes and spaces for gases to exchange.
4. cuticle - the waxy protective coating on leaves.
5. epidermis - the outer layer of cells on leaves that has a waxy coating.
Explanation:
The structure of leaves has various layers and structures in it for specific functions.
Epidermis - it is the outermost protective layer of the leaf that has a waxy coating known as the cuticle.
Cuticle - it is a waxy coating that provides protection to the plant leaves and prevents moisture to move out of the cells.
Palisade layer - it is the closely packed photosynthetic pigments chlorophyll layer known as the primary spot for photosynthesis.
Spongy layer - it is the layer that has loosely packed photosynthetic cells and allows the gaseous exchange as their many small holes and spaces.
Stomata - Stomata is the holes or openings that are most frequently found on the underside of a leaf that allows for gaseous exchange.
From the given options, the following sidovery involving DNA happened first: C) Griffith learned that a chemical changed harmless cells into harmful cells.
The British medical officer named Frederick Griffith discovered DNA in 1928 while conducting experiments using Streptococcus pneumoniae bacteria and mice.
<span>He concluded that the living R bacteria had been transformed into pathogenic S bacteria by an unknown, heritable substance from the dead S cells that allowed the R cells to make capsules.</span>
The rate at which materials enter and leave the cell depends on the cell's surface area.
