Anatomy of Flowering Plants - Online Test
Q1. The tissue present in all organs of plant is
Answer : Option D
Explaination / Solution:
Generally all the organs of plant are made up of parenchyma cells.
Q2. Which meristem contributes to the formation of the primary plant body?
Answer : Option A
Explaination / Solution:
Both apical meristems and intercalary meristems are primary meristems because they appear early in life of a plant and contribute to the formation of the primary plant body.
Q3. Sclerids belongs to
Answer : Option D
Explaination / Solution:
Scleroids belongs to sclerenchyma complex permanent tissue presentin hard parts of plants. They are generally hard and founds in rough fruits and stem.
Q4. The parenchymatous cells which lie between the xylem and the phloem are called
Answer : Option B
Explaination / Solution:
Conjunctive tissue is a narrow strip of tissue ( parenchyma or sclerenchyma) that lies between xylem and phloem bundles of root.
Q5. A speciallised parenchymatous cells, which are closely associated with sieve tube elements is
Answer : Option D
Explaination / Solution:
The companion cells are specialised parenchymatous cells, which are closely associated with sieve tube elements. The sieve tube elements and companion cells are connected by pit fields present between their common longitudinal walls.
Q6. The meristems which occur at the tips of roots and shoots and produce primary tissues are called
Answer : Option B
Explaination / Solution:
Apical meristem is found at the apices, or tips of the plant, both the tip of the shoot and the root, and is a region of actively dividing cells. The definition is easy to remember when you break it down. An apex is the tip, the very end, of something.
Q7. A group of cells having a common origin and usually performinga common function is
Answer : Option C
Explaination / Solution:
A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
Q8. Conjoint type of vascular bundles are common in
Answer : Option C
Explaination / Solution:
In conjoint type of vascular bundles,the xylem and phloem are situated at the sameradius of vascular bundles. Such vascularbundles are common in stems and leaves. Theconjoint vascular bundles usually have thephloem located only on the outer side of xylem.
Q9. Which one is not a xylem cell?
Answer : Option C
Explaination / Solution:
Xylem is a complex tissue, which consists of four kinds of cells. These cells are tracheid, vessels, xylem parenchyma and xylem fibers. Companion cell is part of phloem tissue.
Q10. Which is not the function of parenchymatous cells?
Answer : Option A
Explaination / Solution:
The parenchyma performs various functions like photosynthesis, storage, secretion.
