1. What is tissue?
Answer :
Group of cells that are similar in structure and perform same function is called a tissue. E.g., phloem, xylem, blood are examples of tissue.
2. What is the utility of tissues in multicellular organisms?
Answer :
In multicellular organisms, cells become specialised to perform different functions. Similar cells group together to form tissue for eg. muscular tissue. These tissues perform specific functions, for example, nerve cells carry messages, muscular tissues cause movement, blood flows to transport oxygen etc. Thus, tissues in multicellular organisms show division of labour.
3. Name three types of simple tissues.
Answer :
A simple tissue is made up of only one type of cells. There are three types of simple tissues in plants are:
1) Parenchyma
2) Collenchymas
3) Sclerenchyma.
4. Where is apical meristem found?
Answer :
The apical meristem occurs at the growing tips of roots and shoots and increases the length of the stem and root.
5. Which tissue makes up the husk of coconut?
Answer :
Husk of a coconut is made up of sclerenchymatous fibres.
6. What are constituents of phloem?
Answer :
Phloem is a conducting or vascular tissue of the plants. Phloem is made up of four types of elements: sieve tubes, companion cells, phloem fibres and phloem parenchyma.
7. Name the tissue responsible for the movement in out body.
Answer :
Muscular tissue is a contractile tissue made up of muscles. This tissue is responsible for movement in our body.
8. What does a neuron look like?
Answer :
The cells of the nervous tissue are called nerve cells or neurons. A neuron or nerve cell is structural and functional unit of the nervous tissue (brian, spinal cord and nervous). It consists of cell body which has cytoplasm and a nucleus. Cell organelles such as golgi apparatus, mitochondrial, etc are also present in the cyton. Each neuron has a single long part, called the axon and many short, branched parts called dendrites which help transfer signal from one nerve cell to another.
