Plant Tissues and Animal Tissues

Answer

A tissue is a group of cells that have a common origin, similar structure, and perform a specific function together. For example, muscle tissue is made of muscle cells that contract to produce movemen…

Answer

Histology is the branch of biology that studies the structure, types, and functions of tissues in living organisms.

Answer

The two main types of plant tissues are: (1) Meristematic tissues – made of dividing cells responsible for growth, and (2) Permanent tissues – mature cells that perform specific functions and do not d…

Answer

Meristematic cells are: (1) immature or undifferentiated, (2) living with thin cell walls, (3) closely packed with no intercellular spaces, (4) rich in cytoplasm, (5) have prominent nuclei, and (6) la…

Answer

Apical meristem is at root and shoot tips and causes growth in length. Intercalary meristem is found at the base of leaves or internodes and helps in regrowth after grazing. Lateral meristem lies on t…

Answer

Permanent tissues are groups of mature cells that have lost the ability to divide and are specialized to perform specific functions like storage, support, or conduction. They originate from meristemat…

Answer

The three types of simple permanent tissues are: (1) Parenchyma, (2) Collenchyma, and (3) Sclerenchyma.

Answer

Parenchyma cells are living, isodiametric (equal-sized), with thin cellulose walls and intercellular spaces. They store food, perform photosynthesis (in chlorenchyma), and aid in wound healing and buo…
