Answer:

For calculating the surface to volume ratio for a spherical cell,  

Surface area (S) = 4πr²

Volume (V) = 4πr³ / 3

Ratio = S / V = 4πr² / 4πr³ / 3 = 3 × 4πr² / 4πr³

= 3/r

1. 15 micrometer diameter = Ratio = 3/7.5 = 0.4

2. 2 micrometer diameter = Ratio = 3/1 = 3

The cells exhibiting high surface to volume ratio shows enhanced metabolic activity. Shows easy uptake of oxygen, nutrients, water, and also the excretion of waste as they possess large surface.

What cell organelle makes turgor pressure in a plant cell possible? Describe the role of this organelle in this process.
Brut [27]

Answer:

Explanation: The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

How would expect the biomass to change after ten days if seeds and plants were provided the following conditions?
atroni [7]

Answer:

La biomasa (energía) se refiere a la biomasa «útil» en términos energéticos formales: las plantas transforman la energía radiante del Sol en energía química a través de la fotosíntesis, y parte de esa energía química queda almacenada en forma de materia orgánica; la energía química de la biomasa puede recuperarse quemándola directamente o transformándola en combustible.
