What polysaccharide provides rigidity and strength in plants?

I believe the polysaccharide that provides rigidity and strength in plants would be cellulose. As this is one of the essential components found in the cell wall of plant cells.

Answer:

cellulose

Explanation:

Cellulose can be defined as the polysaccharide that provides plant stiffness and strength. Cellulose stands out for being an insoluble carbohydrate and resistant to various chemical reactions. Moreover, it is the major component of the plant cell cell wall, representing about 30% of the dry mass in primary walls and 50% to 80% in secondary walls.

Cellulose is part of the constitution of the cell wall. Here it ensures stiffness as it forms a large system of interwoven fibers. Although it is formed by the same starch compound, cellulose is not used as an energy source for the vegetable.

Only some organisms are capable of breaking down cellulose molecules for their use, such as bacteria, fungi and some animals. In ruminants, cellulose is used as a source of energy due to the presence of microorganisms in its digestive tract that can break down this product.

Think of any number. Now add 2. multiply by 2. minus 2. divide by2. now minus it by the number u first thought of. The ans is 1.

givi [52]

Answer:

The correct answer is - 1.

Explanation:

Given:

The question says to take a number add 2 multiply 2 minus two and divided by 2 and minus the number thought so the numerical representation would be

=> (if x = 1)

Solution:

According to the ques

2+1 = 3

3*2= 6

6-2= 4

4/2 = 2

2- 1 = 1

Cell Length of one side Area of one side of the cube (l × w) Surface area (area of one side × 6 sides) Volume (l × w × h) Surfac

s2008m [1.1K]

The complete question is as follows:

1. What does a surface area/volume ratio of 6:1 mean for the cell’s ability to get the materials it needs that move across its surface?

2. What does a surface area/volume ratio of 3:1 mean for a cell’s ability to get materials across its membrane, compared to the cell with a ratio of 6:1?

Answer:

1 . Surface area to volume ratio = 3 : 1

surface area= 3 cm³ or (l = 1 cm) (1 cm x 1 cm x 3) (W = 3)

volume= 1 cm³ (1cm x 1cm x 1cm)

2. Surface area to volume ratio = 6 : 1

surface area= 6 cm³ or (1 cm x 1 cm x 6 ) (w= 6)

volume= 1 cm³

Diffusion increases with the increase in surface area to volume ratio through the semi-permeable membrane of the cell membrane that allows substances to move into the cytoplasm
