Question

Answer the following questions:1.Differentiate between sclerenchyma and parenchyma tissues. 2.Why are xylem and phloem tissues called as complex tissues?3.Differentiate between xylem and phloem tissue.4.What are the functions of areolar tissue?5.Which type of tissue makes up the skin of our body? Describe itsstructure.6.Why is blood called connective tissue?7.Where is cartilage present and what is itsfunction?8.What is a nerve?

Answer 1

Answer:

Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees. ... Parenchyma has a thin cell wall of their cells, and are made up of cellulose.

Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions of the xylem and phloem. Tracheids are elongated, thick-walled dead cells with tapering ends

Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue

Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.

others plz u find it I'm bored

Answer 2

Answer:

1. Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees. ... Parenchyma has a thin cell wall of their cells, and are made up of cellulose.
2. Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions of the xylem and phloem. Tracheids are elongated, thick-walled dead cells with tapering ends.
3. Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.
4. Function. Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.
5. The skin is an epithelial membrane also called the cutaneous membrane. It is a stratified squamous epithelial membrane resting on top of connective tissue.
6. Blood is considered a connective tissue because it has a matrix. The living cell types are red blood cells, also called erythrocytes, and white blood cells, also called leukocytes. ... Erythrocytes (red blood cells), the predominant cell type, are involved in the transport of oxygen and carbon dioxide.
7. Cartilage is a flexible connective tissue found in many parts of the body. It can bend a bit, but resists stretching. Its main function is to connect bones together. It is also found in the joints, the rib cage, the ear, the nose, the throat and between the bones of the back
8. Nerves are a part of the nervous system. They are primarily involved in control and the coordination of all the parts of the body.
