You learned that cells are structurally modified so that they can perform their function efficiently and effectively. Which of the following structures have specialized functions due to cell modification?
I.Guard cells
II. Haemoglobin.
III. Trichomes
IV. Xylem vessels
A. I, II and III
B. I, II and IV
C. I, III, and IV
D. I, II, III, and IV
Which of the following statements best illustrate the adaptation and function of nodified cell?
A. The xylem in the leaf helps the leaf to be positioned horizontally towards the sun .
B. The hair-like structure in the root helps to increase the surface area of root hair cell
C. Red blood cell has biconcave for increasing its surface area thus diffusion of oxygen in and out of the cell becomes easy.
D. Guard cells are specialized in such a way that the cell wall in the inner side of the guard cell is thicker than the outer side which makes the guard cell turgid.
Which of the following statement are true?
I. Cell modification is a process that occurs after cell division where the newly formed cells are structurally modified II. Cilia, flagella, and pseudopods are examples apical cell modifications that have a whip like structures .
