What are the characteristics of the tissues which help in the plants growth [500]
- Cells are small
- The cell walls are thin
- Nuclie are large and conspicuous
- Cells are almost without vacoules
- The cells are actively dividing to add new cells
if you mentioned the name of these type of tissues (meristamatic tissues) I will add 100 bonus points

Choose the odd one out and mention why.
i) Ligaments, Cardiac Muscles, Tendons, Aleolar tissue
ii) Parenchyma, collenchyma, epidermis, xylem
iii) Skeletal, Smooth, Cardiac, lymph
iv) node of ranvier, internode, sheath, nucleus
v) Epidermis, squamous epithelial, cork, collenchyma.
i) Cardiac mucles; The rest are fibourus connective tissues
ii) Xylem: the rest are simple permanent tissues
iii) Lymph; it is the only fluid connective tissue
iv) Nucleus is the only part of the nueron found in the cyton.
v)Collenchyma is the only one which is not a covering/protective layer

1. What is the use of protective tissues? Explain with the help of an example.[200]
2. Name the 3 kinds of connective tissue with each of their sub-types. [300]
1. Protective Tissues are vital in a plant to prevent injury and infection. An example is the epidermis, a waxy waterproof coating that provides a protective barrier against mechanical injury, water loss, and infection.
2. Types of connective tissue :
- Supportive connective tissue (cartilage and bone)
- Fibrous connective tissue (areolar, adipose, tendons and ligaments)
-Fluid connective (lymph and blood)

1. Define tissues [300]
2. What is protoplasm [200]
1. A group of cells which are similar in structure, and perform a specific function, form a tissue
2. Protoplasm is a living substance. Consists of the nucleus and cytoplasm.

Name parts 1-5 and state what they do.
1. Dendrites:- Conduct electrical impulses toward the cell body of the nerve cell.
2. Cyton:- It is the cell body
3. Nucleus:- Holds the genetic material
4. Node of Ranvier:- Helps propagate electrical impulses (helps transport the electrical signals)
5. Axon Terminals:- Converts an electrical signal into a chemical signal.

Here are some questions on valscular tissues
i) ______ & _______ are vascular tissues
ii) Bidirectional conduction can be seen in _________
iii) _________ transports water and minerals
iv) _________ consist of dead cells
v) __________ consists of living cells
i) xylem and phloem
ii) phloem
iii) xylem
iv) xylem
v) phloem

1. Why do we need the epithalial tissues? [100]
2. Name the use of each epithelial tissue. [400]
1. Epithalial tissues are vital as the cover the surface of the body and for the lining of various body cavities and internal organs. They help in many important processes as the secrete, absorb and protect our body. (if answer is different I will decide wether to give the points or not.)
2. Uses:-
- Squamous Epithelium: Used for covering and protecting
-Cuboidal Epithelium:They are usually concerned with absorption
-Columnar epithelium:They serete enzymes.
-Ciliated Columnar epithelium: Help in movement of particles.

1. Define non-dividing tissues [300]
2. Where are meristematic tissues found [200]
1. A Permanent tissue {non-dividing tissue} is a group of cells in which growth has either completely stopped or for the time being.
2. They are found in the growing parts of the plant like the tips of the stems and roots. They also help growth in the thickness of the stem.

2. Differentiate between Smooth Muscle tissues and Cardiac muscle tissues [200]
