Do the guard cells in leaf contain chloroplasts?

Answer 1

The leaf and stem epidermis is covered with pores called stomata (sing., stoma), part of a stoma complex consisting of a pore surrounded on each side by chloroplast-containing guard cells, and two to four subsidiary cells that lack chloroplasts.

Guard Cells:
The stoma is bounded by two guard cells. The guard cells differ from the epidermal cells in the following aspects:

The guard cells are bean-shaped in surface vew, while the epidermal cells are irregular in shape
The guard cells contain chloroplasts, so they can manufacture food by photosynthesis (The epidermal cells do not contain chloroplasts)
Guard Cells are the only epidermal cells that can make sugar. According to one theory, in sunlight the concentration of potassium ions (K+) increases in the guard cells. This, together with the sugars formed, lowers the water potential in the guard cells. As a result, water from other cells enter the guard cells by osmosis so they swell and become turgid. Because the guard cells have a thicker cellulose wall on one side of the cell, i.e. the side around the stomatal pore, the swollen guard cells become curved and pull the stomata open.
At night, the sugar is used up and water leaves the guard cells, so they become flaccid and the stomatal pore closes. In this way, they reduce the amount of water vapour escaping from the leaf.

Answer 2

chloroplasts are mainly found in the mesophyll of plant tissue, which is the interior of the leaf. oxygen needs to get to the chloroplast through the stomata, which are on the exterior of the plant, so i would say chloroplasts are probably not in guard cells.

Answer 3

Guard cells do not contain chloroplasts

Answer 4

Chloroplast is used to make ability mutually as the chlorophyll is mixed with image voltaic. An onion is grown below floor so therefor would not get image voltaic. A plant can no longer pass via way of photosynthesis without image voltaic. The leaves and stem that protrude via way of via way of soil have chloroplast of their cells as they're green. mutually as they pass via way of photosynthesis, the flexibility that's made is sent perfect right down to the onion bulb. it extremely is using fact with the objective to be a residing component, it is going to be certain on ability to stay to tell the story.

Answer 5

no i believe they do not. they are mainly just spaces for osmosis to take place so that the become plump and/or flacid so that the stomata make open/close.
