Question

q.1. use the words in the box below to label the major components of a plant cell.
ribosome
nucleus
lysosome
endoplasmic reticulum
mitochondria
cytoplasm
chloroplast
vacuole
golgi apparatus
q.2. fill in the blanks with suitable words.
a) all plants are composed of ______________ cells which have a well - defined nucleus and membrane - bound organelles.
b) ______________ are the organelles that perform photosynthesis in plant cells.
c) plant cells are surrounded by a rigid ______________ that is composed of cellulose.
d) plant cells have a large central ______________ that provides storage of water, food, waste products, and other materials.
e) ______________ contain colorful pigments that give red, orange, and yellow colors to the plant structure. these plastids are found in flowers, fruits, aging leaves, and some roots.
q.3. which of the following organelles is not found in a plant cell?
a) centrosome
b) vacuole
c) ribosome
d) mitochondria
q.4. which of the following structures is a green pigment that captures energy from sunlight?
a) glucose
b) cellulose
c) chlorophyll
d) chromoplast

Explanation:

Q.1: Requires knowledge of plant - cell organelle shapes and functions to label.
Q.2:
a) Eukaryotic cells have a well - defined nucleus and membrane - bound organelles. Plants are eukaryotes.
b) Chloroplasts contain chlorophyll and carry out photosynthesis.
c) The cell wall of plant cells is rigid and made of cellulose.
d) The large central vacuole in plant cells stores water, food, waste, etc.
e) Chromoplasts contain colorful pigments.
Q.3: Centrosomes are mainly found in animal cells, not plant cells. Plant cells have vacuoles, ribosomes, and mitochondria.
Q.4: Chlorophyll is the green pigment in chloroplasts that captures light energy for photosynthesis. Glucose is a product of photosynthesis, cellulose is in the cell wall, and chromoplasts have non - green pigments.
