Study Notes

Plant Tissue and Functions

Xylem conducts water and nutrients from roots to other plant parts, facilitating hydration and nutrient uptake.
Phloem transports sugars produced in photosynthesis from leaves to non-photosynthesizing tissues, ensuring energy distribution.
Lateral roots enhance stability and absorb water and nutrients from the soil, increasing surface area for water uptake.
The apical meristem is found at the tips of roots and shoots, responsible for the primary growth of the plant.

Cellular Structures and Processes

Ribosomes are the cell organelles synthesizing proteins, essential for various cellular functions and activities.
The cell membrane, a selective barrier, regulates the movement of substances in and out of the cell, maintaining homeostasis.
The Golgi Apparatus modifies, sorts, and packages proteins and lipids for secretion or use within the cell, playing a critical role in cellular logistics.
Aerobic respiration occurs in the mitochondria, where energy (ATP) is produced through the breakdown of glucose using oxygen.

Leaf and Flower Structures

Axillary buds are located in the angles between the stems and leaves, capable of developing into new branches or flowers.
The root cap protects the growing tip of the root and helps the root navigate through the soil as it grows.
The petiole connects the leaf blade to the stem, supporting the leaf and facilitating the transport of nutrients and water.
The ovules are contained within the ovary of a flower's pistil, involved in reproduction and seed formation.

Specialized Cell Functions

Chloroplasts are the sites of photosynthesis within plant cells, converting sunlight into chemical energy stored as glucose.
The Rough Endoplasmic Reticulum is studded with ribosomes, facilitating the synthesis and processing of proteins destined for export or for use in membranes.
