Question 14

Question 15

what was observed in this Plasmodesmata in Diospyros endosperm

Answer 15

parenchyma

Question 16

what organell could we not see in trifolium pratense

Answer 16

collenchyma, it had parenchyma, xylem/schlerenchyma, and phloem

Question 17

what were we looking for in blast

Answer 17

schlerenchyma

Question 18

the oak fibres were which type of cell type

Answer 18

schlerenchyma

Question 19

Why do parenchyma cell walls in Trifolium thicken with age?

Answer 19

part of the plant’s natural process of maturation and structural adaptation.

thickening enhances overall structural integrity and support

Question 20

purpose of sclerenchyma cells?

Answer 20

provide mechanical strength and rigidity to the plant. These cells have thick, lignified secondary walls and are typically dead at maturity, making them well-suited for supporting structures such as stems and other plant parts.

Question 21

Why are the bast fiber cells of Linum not stained red unlike most fiber cells

Answer 21

they might not contain lignin, which typically reacts with certain stains to appear red
