Dermal tissue

secretes a waxy film called a cuticle to form a physical barrier between a plant and its environment, reduces water loss and physical damage

Ground tissue

makes up most of plant interior, carries out metabolic processes

Vascular tissue

responsible for transporting water and nutrients around the plant

Parenchyma cells

majority of plant cells, responsible for photosynthesis and other metabolic activity

Sclerenchyma and collenchyma cells

Provide support to the plant

Xylem cells

responsible for transporting water and minerals from the roots to the leaves of the plant

Phloem cells

responsible for transporting sugars and other nutrients throughout the plant

Leaves

Sites of gas exchange and responsible for photosynthesis

Flowers

The sexual reproductive organs of flowering plants (angiosperms)

Fruits

Grown from a flower post fertilisation, protect seeds and often specialised to attract animals that aid with seed dispersal

Stems

Supports leaves, flowers, and fruits, transports water and nutrients between the roots and shoots

Roots

Absorption/storage of water and nutrients from the soil, anchors to the ground and provides structural support

Root system

responsible for providing support to the plant and water/nutrient absorption from soil

Shoot system

made up of reproductive organs, stems, and leaves

Cell

the smallest functional unit of a living organism

Tissue

a cluster of cells that perform a shared function

Organ

a combination of tissues and cells into a distinct structure that performs a specific function

Organ system

a collection of organs and tissues that perform specific functions necessary for survival

Muscle tissue

contracts to exert a force, made up of skeletal, cardiac, and smooth muscle tissue

Nervous tissue

composed of neurons that detect stimuli/carry electrical signals and glia that assist in neuron signal transmission

Connective tissue

connects/supports other tissues and organs of the body

Epithelial tissue

Composes the external and internal layers of the body, assist in protection, secretion, and absorption

why cells in multicellular organisms must work together and coordinate their functions for the organism to survive

to allow specialised cells to perform their roles efficiently, supporting the organism to maintain all functions required to sustain life
