In order to study the formation of cancer cells, you should study the life cycle of normal cells as cancer cells are abnormal cells.
Actually, Normal cells grow, divides and died after an interval of time. And when this process is break down, cancer cells begin to form. They are usually old cells which don't die after their life cycle.
Hope this helps!
Habitats of the plants:
X : winter or cold mountainous habitat
Y : desert habitat
Z: Aquatic habitat
Explanation:
The X plant leave morphology suggests that thick wax coating of leaf helps it to retain water in it. Such plants are called conifers. They are not shed every year so suitable for sunlight to be captured for photosynthesis. In cold regions heavy wind happens cone like leaf is able to resist the winds and prevent it from falling. The cone like structure of leaves help them let the snowfall.
The plant Y leaves and root morphology suggests that it is well suited for dry lands or desert as where less water is there. They store water for longer time when it rains because of the extensive root system. The spine leaves help in reduced transpiration as water scarcity is there.
The plant Z leaves morphology suggests that thin and ribbon structure leaves can help them resist the pressures of flowing water as there are air space in the leaves which provide buoyancy to the leaves.

Answer:
The cell cycle is a cycle of stages that cells pass through to allow them to divide and produce new cells. It is sometimes referred to as the “cell division cycle” for that reason.
New cells are born through the division of their “parent” cell, producing two “daughter” cells from one single “parent” cell.
Daughter cells start life small, containing only half of the parent cell’s cytoplasm and only one copy of the DNA that is the cell’s “blueprint” or “source code” for survival. In order to divide and produce “daughter cells” of their own, the newborn cells must grow and produce more copies of vital cellular machinery – including their DNA.
The two main parts of the cell cycle are mitosis and interphase.
Mitosis is the phase of cell division, during which a “parent cell” divides to create two “daughter cells.”
The longest part of the cell cycle is called “interphase” – the phase of growth and DNA replication between mitotic cell divisions.
Both mitosis and interphase are divided into smaller sub-phases which need to be executed in order for cell division, growth, and development to proceed smoothly. Here we will focus on interphase, as the phases of mitosis have been covered in our “Mitosis” article.
Interphase consists of at least three distinct stages during which the cell grows, produces new organelles, replicates its DNA, and finally divides.

<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.
Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction
Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.
