What is the apex of a cell?
apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.
What is Apex in biology?
In botany, apex refers to the highest point or vertex of a plant stem or root. The shoot apex is where fresh stems, leaves, and other parts of a plant grow after the old parts fall off or dry up. In some cases, such as monocot stems, the shoot apex tends to be more elongated.

Where are Purkinje Fibres?
The purkinje fibres are found in the sub-endocardium. They are larger than cardiac muscle cells, but have fewer myofibrils, lots of glycogen and mitochondria, and no T-tubules. These cells are connected together by desmosomes and gap junctions, but not by intercalated discs. Take a look at this EM of a purkinje cell.

What is projectile motion in Brainly?
Projectile motion is a form of motion in which an object or particle (called a projectile) is thrown near the earth’s surface, and it moves along a curved path under the action of gravity only. The only force of significance that acts on the object is gravity, which acts downward to cause a downward acceleration.
What is basolateral surface?

What is apical and basal?
