Ssc Biology Chapter 2 Hand Note Exclusive -

Bear hair-like cilia on their free surface to move particles (e.g., respiratory tract). 2. Connective Tissue

Dead cells with highly thickened, lignified walls. They provide ultimate mechanical strength. Divided into elongated Fibers and hard, gritty Sclereids (stone cells).

The "exclusive" hand notes emphasize the cell as the basic unit of life, detailing both the physical structures and the biochemical processes that sustain them. Cell Theory:

Cube-shaped cells with central, spherical nuclei (e.g., kidney tubules). Specialized for secretion and absorption. ssc biology chapter 2 hand note exclusive

Network of membranes for transport (Rough ER = has ribosomes, Smooth ER = no ribosomes). Golgi Bodies: Packaging and secretion of materials. Lysosomes: "Suicide Squad." Contain digestive enzymes [3]. 2. Animal Tissues (Exclusive Classification)

Short, branched extensions that receive incoming electrical signals. Bear hair-like cilia on their free surface to

Contains DNA; becomes chromosomes during division.

Found in plants; Chloroplasts are essential for photosynthesis. Ribosomes: Sites for protein synthesis.

Protoplasm includes everything inside the cell wall (including the nucleus). Cytoplasm is the protoplasm excluding the nucleus. They provide ultimate mechanical strength

Cells that possess the continuous capability of mitotic division. They are characterized by thin cell walls, dense cytoplasm, large nuclei, and an absence of intercellular spaces or vacuoles. They drive primary and secondary plant growth. 2. Permanent Tissue

Be prepared to write comparative differentiation tables for: Plant Cell vs. Animal Cell Xylem vs. Phloem Striated Muscle vs. Non-striated Muscle vs. Cardiac Muscle

: Derived from meristematic tissue that has lost the ability to divide.
