autotrophs
manufacture food molecules from simple, inorganic sources by the process of photosynthesis using light as a source of energy
1 of 10
all plants
contain the light-absorbing pigment chlorophyll inside cells which have a definite cellulose cell wall
2 of 10
the plant kingdom
algae, mosses, ferns and seed plants
3 of 10
angiosperms
a flowering, fruit-bearing plant or tree known for having ovules develop within an enclosed ovary
4 of 10
monocotyledons
a single cotyledon in the seed, which produces one seed leaf, and eventually parallel veins on their leaves
5 of 10
dicotyledons
two cotyledons in the seed, which produces two seed leaves, and eventually branched veins on their leaves
6 of 10
features of an angiosperm
flower - the colour, pattern, shape, scent and nectar may attract other small animals, ovary - protects the ovules and developing embryo, especially from drying out, fruits - are formed from ripened ovaries with special features to aid dispersal
7 of 10
features of an angiosperm II
vascular system - transports water, ions and organic solutes, extensive root systems - anchor the shoot systems and absorb water and ions, leaf surface - large to allow high rate of photosynthesis to supply energy for growth and fruit production
8 of 10
large leaf surface
although it allows for a high rate of photosynthesis, it also allows water losses by evaporation and diffusion through the stomata
9 of 10
photosynthesis
the complex process by which carbon dioxide, water, and certain inorganic salts are converted into carbohydrates, using energy from the sun and chlorophyll
