A relatively small area with numerous endemic species and a large number of endangered or threatened species is called a _______
nekit [7.7K]

A biodiversity hot spot is a relatively small region with a significant number of indigenous species and endangered or vulnerable species.

Ecologically distinct areas with extraordinarily high species densities are known as biodiversity hotspots, and they are thus top priorities for nature conservation. The term "biodiversity" has several meanings. A species area must satisfy two severe requirements in order to be considered a biodiversity hotspot: It must have a significant proportion of plant life that is endemic, or found nowhere else on the earth, and at least 1,500 vascular plants. In other terms, a hotspot is unique.

The various parts of the endomembrane system serve different functions in the cell. In this activity, you will identify the role
liberstina [14]

Answer:

Smooth ER:

Lipid synthesis, Calcium ion storage, Poison detoxification

Rough ER:

Protein synthesis

Golgi apparatus:

Protein modification and storage, Cisternal maturation

Lysosomes:

Autophagy, Macromolecule digestion

Explanation:

The endomembrane system is important for the production, processing, and transport of proteins and lipids in the cell.

The smooth ER:

It aids basically in lipid production and processing.

The smooth endoplasmic reticulum, or smooth ER, is an organelle that is observed in animal cells and plant cells. Itd basic function is the production of cellular products such as hormones and lipids.

The rough ER :

It is the spot of secretory protein production.

Rough endoplasmic reticulum is observed in eukaryotic cells. Its basic aid is to synthesize proteins. It consists of cisternae, tubules and vesicles. The cisternae comprise of flattened membrane disks, that play a major role in protein modification.

Golgi apparatus:

It helps in further processing of the proteins produces for the rough ER and then in sending them off in vesicles to the plasma membrane.

It's often termed the cell's post office. It modifies, sorts and arrange proteins for secretion. It aids lipid transportation around the cell, and the production of lysosomes.

Lysosomes:

Its enzymes are synthesized and formed in the rough ER and Golgi apparatus. It aid hydrolysis of macromolecules e.g. phagocytosis and autophagy.

It is involved in digestion and waste removal by feeding on worn-out organelles, food molecules, and engulfed viruses or bacteria.
