Multiple Choice Questions
1A tissue is best defined as:
(a) A group of organs
(b) Similar cells working together for a function
(c) One cell performing all functions
(d) Several organ systems
(b) is correct
Division of labour begins when similarly structured cells cooperate to perform a specific function.
2Which tissue causes an onion root to increase in length?
(a) Lateral meristem
(b) Apical meristem
(c) Sclerenchyma
(d) Phloem
(b) is correct
Apical meristem at root and shoot tips produces primary growth in length.
3Increase in the girth of a woody stem is mainly due to:
(a) Intercalary meristem
(b) Lateral meristem
(c) Epidermis
(d) Parenchyma
(b) is correct
Lateral meristems such as cambium add cells sideways, increasing thickness.
4Which meristem helps grass regrow after grazing or cutting?
(a) Apical
(b) Lateral
(c) Intercalary
(d) Cork
(c) is correct
Intercalary meristem occurs near nodes or leaf bases and restores length.
5Meristematic cells usually have:
(a) Thick lignified walls and no nucleus
(b) Dense cytoplasm and active division
(c) Large intercellular spaces
(d) A large permanent vacuole
(b) is correct
These living, compact cells retain the ability to divide actively.
6Which simple permanent tissue mainly stores food and may perform photosynthesis?
(a) Parenchyma
(b) Sclerenchyma
(c) Xylem
(d) Cork
(a) is correct
Parenchyma is living tissue used for storage; chlorenchyma also photosynthesises.
7Which tissue gives flexible support to young plant stems?
(a) Collenchyma
(b) Sclerenchyma
(c) Phloem
(d) Epidermis
(a) is correct
Unevenly thickened collenchyma cells support young parts while allowing bending.
8Coconut husk is tough mainly because it contains:
(a) Parenchyma
(b) Sclerenchyma fibres
(c) Guard cells
(d) Meristem
(b) is correct
Thick, lignified sclerenchyma walls provide great mechanical strength.
9Which complex tissue transports water and minerals upward in plants?
(a) Phloem
(b) Xylem
(c) Epidermis
(d) Collenchyma
(b) is correct
Xylem conducts water and dissolved minerals and also contributes support.
10Which tissue transports prepared food in plants?
(a) Xylem
(b) Phloem
(c) Sclerenchyma
(d) Cork
(b) is correct
Phloem distributes sugars and other organic nutrients.
11The opening and closing of stomata are controlled by:
(a) Guard cells
(b) Xylem vessels
(c) Sieve tubes
(d) Nerve cells
(a) is correct
Guard cells change shape to regulate the stomatal pore and gas exchange.
12Which animal tissue covers body surfaces and lines organs?
(a) Muscular
(b) Epithelial
(c) Nervous
(d) Connective
(b) is correct
Epithelial tissue forms protective coverings and linings.
13Blood is classified as connective tissue because it:
(a) Contracts to move bones
(b) Connects body parts by transporting substances
(c) Covers the skin
(d) Produces nerve impulses
(b) is correct
Its fluid matrix carries gases, nutrients, wastes and signals throughout the body.
14Which connective tissue joins muscle to bone?
(a) Ligament
(b) Tendon
(c) Cartilage
(d) Adipose tissue
(b) is correct
Tendons are strong cords that transmit the pull of muscles to bones.
15Which structure joins one bone to another at a joint?
(a) Tendon
(b) Ligament
(c) Neuron
(d) Xylem
(b) is correct
Ligaments stabilise joints by connecting bones.
16Which muscle type is striated, voluntary and attached to bones?
(a) Smooth muscle
(b) Cardiac muscle
(c) Skeletal muscle
(d) Epithelial tissue
(c) is correct
Skeletal muscles are under conscious control and move the skeleton.
17Which muscle is branched, striated and involuntary?
(a) Cardiac muscle
(b) Smooth muscle
(c) Skeletal muscle
(d) Tendon
(a) is correct
Cardiac muscle forms the heart wall and contracts rhythmically without conscious control.
18The specialised cell that carries electrical messages is a:
(a) Neuron
(b) Osteocyte
(c) Guard cell
(d) Adipocyte
(a) is correct
Neurons receive and transmit impulses for coordination.
19Which type of joint permits movement in many directions at the shoulder?
(a) Hinge joint
(b) Pivot joint
(c) Ball-and-socket joint
(d) Fixed joint
(c) is correct
The rounded head fits into a socket, allowing movement in several planes.
20Which joint mainly allows bending and straightening at the elbow?
(a) Hinge joint
(b) Pivot joint
(c) Fixed joint
(d) Ball-and-socket joint
(a) is correct
A hinge joint mainly permits motion in one plane, like a door hinge.
