Which of the following is a true statement about number of stomata and rainfall? a.) The amount of rain does not affect the amount of stomata. b.)The more rain, the fewer stomata . c.)The less rain, the more stomata . d.)The less rain, the fewer stomata. Answer Save. 2 Answers. Relevance.Which of the following statements is not true for stomatal apparatus? Options (a) Inner walls of guard cells are thick (b) Guard cells invariably possess chloroplasts and mitochondria (c) Guard cells are always surrounded by subsidiary cells (d) Stomata are involved in gaseous exchange. Correct Answer: Guard cells are always surrounded byWhich statement is NOT true about stomata? A. as guard cells become turgid, the stomates open B. there are two guard cells around each stomate C. guard cells take up potassium ions and water enters the guard cells D. the blue light component of sunlight is a signal that can cause stomata to closeA) Stomata are not important in algae because they do not need CO 2.: B) Stomata, when closed, allow CO 2 to diffuse into plants.: C) Stomata are important in terrestrial plants because they allow CO 2 to diffuse into the plant.: D) Stomata are important in terrestrial plants because they allow the roots to absorb water and nutrients from the soil.B is the right answer as no. of stomata is more on lower epidermis of the leaf.The upper epidermis has less stomata because the palisade mesophyll cells are present on the upper surface.In this way...

Which of the following statements is not true for stomatal

Which of the following statements about stomata is accurate? A) Stomata are not important in algae because they do not need CO2. B) Stomata, when closed, allow CO2 to diffuse into plants. C) Stomata are important in terrestrial plants because they allow the roots to absorb water and nutrients from the soil.Favorite Answer It depends on the species of plant you are dealing with. Some plants (like water lilies) float on water and so have no stomata on the underside. Plants in arid (hot and dry)...The stomata are bordered by two specialized epidermal cells - the guard cells which in some cases are accompanied by subsidiary cells. The walls of guard cells are unevenly thickened. Each guard cell has thick, inelastic inner wall and thin, elastic outer wall. Stomatal aperture is present in between the guard cells.Which of the following statements is not true about stomata? A. As guard cells become turgid, the stomata open. B. There are two guard cells around each stoma. C. Guard cells take up potassium ions and water enters the guard cells. D. Guard cells surrounding stomata lack chloroplasts that other epidermal cells contain.

5. Which of the following statements about stomata is false? (a) Stomata are found in the epidermis of leaves (b) Stomata are found in all land plants except liverworts (c) The opening and closing of stomata is controlled by guard cells (d) When stomata are opened, CO 2 enters and water exits by diffusion (e) The majority of plants open their stomata at nightWhich of the following statements about algae and plants is true? ( Concept 29.1) A)Plants have a waxy, waterproof cuticle, and algae do not. B)Plants are multicellular, whereas algae are unicellular. C)Algae have different types of chlorophyll molecules from plants. D)Both plant and algal zygotes develop into embryos.Which statement is false regarding the guard cells? 1. are specialized epidermal cells 2. are located primarily on the lower epidermis 3. surround the stomata 4. they close the stomata when filled with water 5.volume increases when potassium ions (K+) enterThe stomata consist of minute pores called stoma surrounded by a pair of guard cells. Stomata, open and close according to the turgidity of guard cells. The cell wall surrounding the pore is tough and flexible. The shape of guard cells usually differs in both monocots and dicots, though the mechanism continues to be the same.Stomata must open to allow air containing carbon dioxide and oxygen to diffuse into the leaf for photosynthesis and respiration. When stomata are open, however, water vapor is lost to the external environment, increasing the rate of transpiration. Therefore, plants must maintain a balance between efficient photosynthesis and water loss.
