Plant and Animal Tissue Identification

The video tutorial explains the different types of tissues found in plants and animals, including parenchyma and sclerenchyma in plants, and striated muscle fibers and nerve cells in animals. It provides detailed procedures for identifying these tissues using a compound microscope and describes their unique characteristics and functions.

What is the primary function of tissues in both plants and animals?

• To aggregate cells with similar structure and function

• To provide energy

• To protect against diseases

• To transport nutrients

Which of the following materials is required to identify plant tissues under a microscope?

• Test tubes

• Petri dishes

• Permanent slides of tissues

• Glass slides

What characteristic of parenchyma cells helps in photosynthesis?

• Thick cell walls

• Large vacuoles

• Isodiametric shape

• Presence of chloroplasts

What is the main structural feature of parenchyma cells?

• Elongated shape

• Thick cell walls

• Isodiametric shape

• Presence of sclereids

What is the main role of sclerenchyma cells in plants?

• Providing mechanical strength

• Transporting water

• Photosynthesis

• Storage of nutrients

Which of the following is a characteristic of sclerenchyma fibers?

• They are loosely packed

• They have thick walls

• They contain chloroplasts

• They are isodiametric

Which type of animal tissue is characterized by multinucleated fibers?

• Nerve cells

• Epithelial cells

• Striated muscle fibers

• Smooth muscle fibers

What is the function of the myelin sheath in nerve cells?

• To protect the nucleus

• To store nutrients

• To provide structural support

• To conduct impulses faster

Which part of the nerve cell conducts impulses towards the cell body?

• Dendron

• Axon

• Myelin sheath

• Cyton

What is the appearance of striated muscle fibers under a microscope?

• Smooth and uniform

• Striped with alternate light and dark bands

• Branched and interconnected

• Circular and compact
