What are the types of plant tissues?

Plant tissues: (1) Meristematic tissue — actively dividing cells at growing points (apical, lateral, intercalary). (2) Permanent tissue — simple (parenchyma, collenchyma, sclerenchyma) and complex (xylem, phloem). Xylem and phloem form the vascular bundle and are responsible for transport.

What are the four types of animal tissues?

Four types: (1) Epithelial — covers surfaces and lines organs (skin, intestine lining). (2) Connective — connects and supports (blood, bone, cartilage). (3) Muscular — enables movement (striated/voluntary, smooth/involuntary, cardiac). (4) Nervous — transmits electrical signals (neurons).

What is the difference between striated and smooth muscle?

Striated (skeletal) muscle: has cross-striations, multinucleate, voluntary control, found in limbs and body wall. Smooth muscle: no striations, spindle-shaped, involuntary (automatic) control, found in intestines, blood vessels, uterus. Cardiac muscle is striated but involuntary — found only in the heart.

Plant and Animal Tissues

Tissues • Class 9 Science • NCERT • CBSE

A tissue is a group of cells that are similar in structure and work together to perform a specific function. Plants have meristematic tissues (dividing) and permanent tissues (non-dividing). Animals have epithelial, connective, muscular, and nervous tissues.

Key Formulas

Xylem: conducts water upward (dead cells)
Phloem: conducts food bidirectionally (living cells)
Meristematic tissue formula 2n²: apical, lateral, intercalary
