A plant cell includes a Cell Wall, Cell Membrane, Cytoplasm, Nucleus, Chloroplast, Mitochondria, Vacuole. Each of these parts play unique roles in plant growth and survival, with tasks ranging from providing structure and protecting the cell, to performing photosynthesis and producing energy.
A plant cell is the structural and functional unit of plants that performs various biological functions. The cell has many parts, each with unique functions.
1) Cell Wall: This is the outermost layer providing structure, support and protection to the cell.
2) Cell Membrane: It controls the movement of substances in and out of the cell.
3) Cytoplasm: It contains all the organelles and is where most cellular activities occur.
4) Nucleus: It controls cell activities and contains the genetic material DNA.
5) Chloroplast: This is where photosynthesis takes place.
6) Mitochondria: They produce energy for the cell through respiration.
7) Vacuole: It stores water, nutrients and waste products.
Every part of the plant cell plays a crucial role in plant growth and survival.

Taxonomy is the classification of organisms into a system that indicates natural relationships (evolutionary relationships). This theory describes, names, and classifies organisms.
According to evolutionary history and taxonomy, tigers resemble gorillas more closely than they resemble fish.
b. placing an adult nucleus in a cell without a nucleus.
c. genetically modifying an embryo.
d. isolating cells to learn more about how they specialize
to withstand the pressure of the blood that is being pumped by the heart
to pull the blood back to the heart from all areas of the body
to withstand changes in blood temperature
Arteries need to be thick, muscular and elastic IN ORDER TO WITHSTAND THE PRESSURE OF THE BLOOD THAT IS BEING PUMPED BY THE HEART.
The walls of the arteries are thicker and more muscular than that of veins because of the work that they perform. The arteries have thick and muscular walls, which help them to withstand and absorb the pressure waves that are generated as a result of blood pumping from the heart. The elasticity of the arteries help them to generate appropriate pressure for supporting blood flow.
b_All the atoms lie in a line.
c_The bonds orient in a tetrahedral fashion.
d_All the atoms lie in a plane.
e_The groups rotate around the C=C bond.
Two C atoms form a double bond. Each C is bound to two H atoms. All the atoms lie in a plane. Thus option D is true.
The atom is the basic unit of a matter, it consist of three sub atomic components such as proton, neutron and electron, where proton and neutron present at the central nucleus of atom and electron surround the nucleus.
Proton is positively charged, neutron is neutral and electron is negatively charged; the total number of protons in an atom called as proton number or atomic number which is denoted by the capital letter Z
This number is always a whole numbers range from 1 to 118 according to periodic table element and in an electrically neutral atom the number of electrons is equal to the atomic number.
Thus option D is true.

Answer:
All the atoms lie in a plane
- the double bond limits all the atoms to a plane
