Answer: Option A. -> Parenchyma tissue
:
A
Parenchyma cells have thin walls.They are live cells. They are usually loosely packed,andlarge intercellular spacesare found in this tissue.Therefore, the slide consists of parenchyma cells.
Sclerenchyma is the tissue which makes the plant, hard and stiff. Aerolar tissue and epithelium are animals tissues.

Answer: Option B. -> False
:
B
The amount of dead tissue is more in plants than animals. Manyessential functions in plants are attributedto dead tissues. Dead tissue provides support andmechanical strength to plants, e.g., sclerenchyma. Apart from this, the main conducting tissue in plants, xylem is mostly composed of dead cells.

Answer: Option B. -> Epithelial tissue
:
B
The covering or protective tissues in the animal body are epithelial tissues. Epithelium covers most organs and cavities such as the skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules.

Answer: Option C. -> Xylem and phloem
:
C
Xylem and phloem together form the vascular bundle. They are called conducting tissues. Vascular or conductive tissue is a distinctive feature of the complex plants. Parenchyma, collenchyma and sclerenchyma on the other hand form the simple permanent tissue (ground tissues).

Answer: Option B. -> Blood, phloem and muscle
:
B
A group of similar cells with a common origin specialised to perform a common function are called tissues. E.g., Blood, phloem, muscle, xylem, etc.Various tissues organise to form an organ. Organs, such as heart, lungs, stomach, kidneys, skin, liver, etc are made up of two or more types of tissues organised to serve a particular function. The organs organise to form an organ system.

Answer: Option C. -> By the presence of cells with thick cell walls.
:
C
Sclerenchyma is a dead simplepermanent tissue in plants. The walls of sclerenchyma cells are thick due to the deposition of a complex sugar called lignin. For example, husk of a coconut. Parenchyma tissue on the other hand, is a living tissue. It consists of relatively unspecialised cells with thin cell walls.

Answer: Option B. -> Ability to divide actively
:
B
Plant tissues are broadly classified into meristematic and permanent tissues, based on their ability to divide. Meristematic tissues are group of cells, which have the ability to divide. This tissue consists of small, cuboidal anddensely packed cells, which keeps on dividing to form new cells.The tissues, which are derived from the meristematic tissues, are calledpermanent tissues. They are the tissues, which have lost their ability to divide as they have attained their mature form.

Answer: Option D. -> Sclerenchyma
:
D
Sclerenchyma is the tissue which makes the plant hard and stiff. The husk of a coconut is made of sclerenchymatous tissue. The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin.
