Animal and plant tissues are fundamental components of organisms,
but they exhibit significant differences in structure, function, and
organization. Here are detailed notes highlighting the distinctions
between animal and plant tissues, along with important guidelines
for students:
1. Definition:
Animal Tissue:
Animal tissues are groups of similar cells organized to perform specific
functions within an animal's body.
They are primarily responsible for the structure, support, and
functioning of animal organisms.
Plant Tissue:
Plant tissues are groups of similar cells organized to perform specific
functions within a plant.
They are essential for plant growth, development, and adaptation to the
environment.
2. Cell Wall:
Animal Tissue:
Animal cells lack cell walls. Instead, they are surrounded by a flexible
cell membrane or plasma membrane.
Plant Tissue:
Plant cells have rigid cell walls made of cellulose, providing structural
support and protection.
3. Cell Shape:
Animal Tissue:
Animal cells come in various shapes, often irregular, based on their
specialized functions.
Plant Tissue:
Plant cells typically have a fixed rectangular or square shape, given the
rigidity of the cell wall.
4. Motility:
Animal Tissue:
Animal tissues often contain cells capable of movement, such as muscle
cells and nerve cells.
Plant Tissue:
Plant tissues do not generally possess cells with the ability to move.
5. Vascular Tissue:
Animal Tissue:
Animals do not have specialized vascular tissue systems for the
transport of nutrients and water.
Plant Tissue:
Vascular tissue systems, xylem and phloem, are present in plants for
