The very function, or job of CELL MEMBRANES is to protect the cell from it's surroundings, or in other words, to keep it safe. It controls the movement of substances in and out of cells and organelles, like a guard watching for suspicious activity and protecting something.

The cell membrane itself is a thin, flexible layer around the cells of all living things. It separates the inside of the cells from the outside of the cells.

Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish

sattari [20]

Answer:

Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.

Explanation:

Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.

According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.

What are the differences between prokaryotic and eukaryotic cells? Focus on cells from microscopy lab?

pishuonlain [190]

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

There are several key differences between prokaryotic and eukaryotic cells. Eukaryotic cells are found in multicellular plants and animals, whereas prokaryotic cells are found in bacteria and archaea which are ususlly unicellular. I have summarised the key differences below:

Prokayotic cells do not have membrane-bound organelles, such as the endoplasmic reticulum or mitochondria.

Prokaryotic cells do not have a nucleus, instead they have circular DNA that is free in the cytoplasm.

Prokaryotic cells have smaller ribosomes than eukaryotic cells.

Prokaryotic cells have a cell wall. Their cell wall is made from a different material to a plant cell, a glycoprotein called murein.

Prokaryotic cells may also have a protective layer called a capsule, flagellum to aid in movement and one or more plasmids.
