Organelles Present in Plant Cell Only

Located external to the plasma membrane

A rigid covering that protects the cell, provide structure support, and gives shape to the cell

Cell Wall Composed of

Rigid Regular and definite shape

CELL WALL Main component:

Cellulose microfibrils: made of

Long Chain: monomer glucose → (located external to the plasma membrane)

: glucose we easily take from foods we eat

Short Chain: : beta glucose

CELL WALL End product:

CELL WALL Releases: — → condensation reaction through glycosidic bond

Small channels that directly CONNECT the CYTOPLASM of neighboring plant cells to each other, establishing LIVING BRIDGES between cells

Opening of 2 cells

Chloroplast Large organelles (5 to 10 micrometer long) that are bounded by a double membrane called the —

Has their own DNA and ribosome

Carry out photosynthesis

: light reaction

: dark reaction; utilize the products of the light reaction, the end product is —

Grana and stroma are

: singular for grana

: found in the chloroplast, help ABSORB SUNLIGHT in order for photosynthesis, stack of grana

Central Vacuole Consists of two parts:

: a fluid found in the vacuoles

: membrane - phospholipid later

Storage of water and molecules

Plays a key role in REGULATING THE CELLS’ CONCENTRATION of water in changing environmental condition

Regulates water concentration Gives rigidity

: water exerts pressure to the cell wall

Vacuole is —: less turgor pressure
