Answer 6

Different type of cells.
👉🏻xylem

1️⃣promeristem 
2️⃣1 °-meristem 
3️⃣2 °-meristem
4️⃣plate meristem

Answer 7

Promeristem.

Question 8

1 °-meristem originates from

Answer 8

Promeristem.
# it gives rise to 2 ° meristem.
#for example intra-fascicular meristem

Question 9

Give examples of 2 ° meristem

Answer 9

Inter-fascicular cambium.
Cork cambium.
Cambium in dicots.

Question 10

Cells divide anti-clinally in
1️⃣Rib/file meristem
2️⃣Plate meristem
3️⃣Mass meristem

Answer 10

Rib/file meristem .

*Helps in formation of lateral roots.

Question 11

Cells divide periclinally in plate meristem. (T/F)

Answer 11

True.

Cells divide periclinally( in a plane ⊥ to another) in plate meristem.

Question 12

In mass meristem cells divide 
1️⃣Periclinally
2️⃣Anti-clinally 
3️⃣Both periclinally and anticlinally 
4️⃣Do not divide

Answer 12

Both periclinally and anti-clinally.

Question 13

Longest cells in plant body are

Answer 13

Fibres.

Question 14

Sclerieds are found in

Answer 14

In fruit walls of nuts.
Seed coat of legumes.
Leaves of tea.

Question 15

Coir of coconut is a true fibre. Why?

Answer 15

Bcz its lignified.

Question 16

Short fibres are called 
1️⃣Fuzz
2️⃣Lint
3️⃣Perivascular fibres
4️⃣Libriform fibres

Answer 16

Fuzz

Question 17

Lint is 
1️⃣Long fibre
2️⃣Not true fibre
3️⃣Non lignified
4️⃣Used in cloth making

Answer 17

All of these.

Lint is a long fibre, non lignified, therefore not true and is used in cloth making.

Question 18

Xylary fibres are 
1️⃣In xylem
2️⃣Hard fibres 
3️⃣Can’t be knitted 
4️⃣Not more useful

Answer 18

All of these.

Xylary fibres are found in xylem, are hard and this can’t be knitted therefore not much useful.

Question 19

Bast fibres are 
1️⃣Commercial fibres
2️⃣Phloem fibres
3️⃣Can be knitted
4️⃣Have great economic value.

Answer 19

All of these.

Bast (phloem) fibres are commercial fibres that can be knitted, this have great economic value.

Question 20

Which of these are living mechanical tissue:
1️⃣Parenchyma
2️⃣Collenchyma
3️⃣Sclernchyma
4️⃣N.O.T

Answer 20

Parenchyma and collenchyma are living mechanical tissue.

Sclernchyma is DEAD mechanical tissue.

Question 21

Thick and lignified cell wall is found in Sclernchyma .

T/F

Answer 21

True

Question 22

Cells are thickened at corners due to cellulose, hemicellulose, pectin deposition, in which simple permanent tissue?

Answer 22

Collenchyma

Question 23

Cells of which simple permanent tissue have no secondary depositions?

Answer 23

Parenchyma

Question 24

Collenchyma is found in
A) Most of the dicots.
B) Not in roots and monocots.

Answer 24

Both are correct.

Collenchyma is found in most of the dicots but NOT in roots and monocots.
