Tissues - MCQ Test (22-11-2017) - Class 9 MCQ

Complex tissue consists of different types of cells carrying out the same function. They help in transportation of organic material ,water and minerals.In plants xylem and phloem are example of complex tissues.

Epidermis in plants provides protection, regulation of transpiration and formation of insulation stationary air layer with the help of hair on the surface of it.

Bone consists of cells called Osteocytes. Bone is a specialized connective tissue. Osteocytes are present between the lamellae in fluid filled spaces called lacunae.

Alveolar tissue is known as packaging tissue. These tissues are responsible for storing materials not required by our body at particular time like glycogen.

Phloem is complex tissue consists of sieve tube, companion cells, phloem parenchyma and phloem sclerenchyma (fibre). In which phloem sclerenchyma is non-living.

The husk of coconut is made up of sclerenchyma tissue. Sclerenchyma is simple permanent tissue that provides mechanical support to parts of the plant.

Blood is flood connective tissue that helps in transport of oxygen and carbon dioxide. Haemoglobin present in RBC is responsible for oxygen transport.

Alveolar tissue is known as packaging tissue. These tissues are responsible for storing materials not required by our body at particular time like glycogen.

Sclerenchyma is permanent tissue present in different parts of plants. They are thick walled and do not possess living protoplasm at maturity because these are dead.

Parenchyma tissue is present in all parts of plants that include cortex, flower, stem, leaves and pith. These tissues are thin walled and living.

Blood is flood connective tissue that helps in transport of oxygen and carbon dioxide. Haemoglobin present in RBC is responsible for oxygen transport.

Heart muscles are called cardiac muscles. These muscles are involuntary, striated and uninulcleate. Cardiac tissue pumps blood form birth till death.

Phloem in plants is responsible for conduction of food prepared in leaves to all other parts of plants. Sieve tube and companion cells are mainly responsible for transport of food in phloem.

Parenchyma, collenchyma and sclerenchyma are simple permanent tissue present in different parts of plants. Parenchyma and collenchyma are living but sclerenchymas are dead cells.

Nervous tissue consists of nerve cells or neuron. Dendrite present on cell body receive stimulus and cyton converts stimulus into nerve impulses and carries impulses through axon.

Squamous epithelium tissue is found in alveoli of lung and other parts of plants where regular contraction and relaxation takes place.

Apical Meristematic tissues are found in root tips, shoot tips to increase the length of root, stem.

Apical meristem is present on the root and shoot tips that is responsible for growth in length of root and stem.

Skeletal muscles get fatigued very soon. Skeletal muscles are responsible for movement in different part of the body.

Stratified squamous epithelium occurs in buccal cavity, pharynx etc. germinal epithelium are present in ovary and testis that produce female and male gametes.

In desert plants, rate of water loss gets reduced due to presence of cuticle on leaves surface. Water is mostly lost in form of water vapour during transpiration.

The common name of xylem is wood.

Lymphocytes of white blood cells are most abundant in lymph. Lymph are extracellular fluid that contain WBC but RBC in it.

Totipotancy is the ability of plant parts to develop whole plant. In monocot stems, intercalary meristem is located at the base of internodes and parenchyma contains isodimatic cells but cambium has no apical meristem.

The chemical deposited on the wall of sclerenchyma is lignin. This deposition of lignin on wall makes these tissues impervious to water and air.

Movement in our body is mainly caused by muscular tissue. Skeletal muscular tissues are joined with bones that cause movement due to contractile nature.

Meristematic tissue is present in plant cells but absent in animal cells. Meristematic tissues have ability to divide and mostly present in apical shoot and root tips.

Collenchyma consists of cells having thick walled cells only on corner but sclerenchyma has thick walled cells devoid of cytoplasm. So, collenchyma differs from sclerenchyma in retaining cytoplasm at maturity.

Voluntary muscles are muscles that are under conscious control. They are responsible for performing activities that we can control or initiate voluntarily. Among the given options, the activity that involves voluntary muscles is:

Therefore, out of the given options, writing with the hand is the activity that involves voluntary muscles.
