MICROANATOMY

Detailed explanation-1: -During G 1start subscript, 1, end subscript phase, also called the first gap phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps.

Detailed explanation-2: -In G1, cells accomplish most of their growth; they get bigger in size and make proteins and organelles needed for normal functions of DNA synthesis.

Detailed explanation-3: -A cell grows during the G1 phase of the cell cycle. During this phase, more organelles are produced, a high amount of protein synthesis occurs and the volume of the cytoplasm increases. The cell continues to grow further in the G2 phase.

Detailed explanation-4: -Interphase consists of three steps: G 1start subscript, 1, end subscript phase: first gap phase; the cell grows larger and organelles are copied. S phase: synthesis phase; the cell synthesizes a complete copy of the DNA in its nucleus.
