Plants do need food for their survival and they would not wait or depend on others to provide them with food. There is a particular mechanism in plants with which they prepare their food. This mechanism is known as Photosynthesis. Photosynthesis occurs mainly in leaves of specialized cell structures known as chloroplasts.

Forces that act on a body directly or through a connector are called contact forces., e.g., muscular force, frictional force, mechanical force, etc.
Forces which do not make direct contact with a body but act through space are called non-contact forces, e.g., gravitational force, electric force, magnetic force, etc.

Mercury does not react with non-oxidizing acids but does react with concentrated nitric acid, HNO3, or concentrated sulphuric acid, H2SO4, to form mercury(II) compounds together with nitrogen or sulphur oxides. Mercury dissolves slowly in dilute nitric acid to form mercury(I) nitrate, mercurous nitrate, Hg2(NO3)2. Mercury tends to react with particular groups of elements or compounds. Mercury also reacts with oxygen at high temperatures to form mercury (II) oxide, which is a red powder. Similarly, mercury reacts with oxidizing acids, such as nitric acid and concentrated sulfuric acid, because they contain oxygen.

The human eye is an organ that reacts to light and allows vision. Rod and cone cells in the retina allow conscious light perception and vision including color differentiation and the perception of depth. Made of many working parts, the human eye functions much like a digital camera. ... Its job is to convert images into electronic signals and send them to the optic nerve. The optic nerve then transmits these signals to the visual cortex of the brain which creates our sense of sight.

Damaging the cell membrane like to impact the functions of the cell because cell membrane acts as a semi-permeable membrane which allows the entry and exit of some materials in and out of the cell. Thus, the functional properties of the cell will lost and the cell will die.
Cell membrane acts as a semi permeable membrane. It controls the amount of substance going inside and coming outside the cell. It acts as a barrier and separates the cell from the external environment. Many toxic substance cannot enter the cell due to cell membrane. The integrity of the cell i.e the size and structure of tue cell is maintained by cell membrane.
Therefore damage to the cell membranes can lead to entry of toxic substance inside the cell which can destroy the nucleus and other cell organelles.

The reason why frogs lay so many eggs is to increase the chances of survival for the hatchlings, because they have many predators such as snakes, birds and turtles to eat them up.
Because external fertilization takes place in frogs and fishes and in external fertilization there is a high risk
many eggs get vanished due to action of wind, water,predators etc. so if they lay less eggs then fertilization does not takes place.
