General Characteristics
What is the name of the process that plants perform in which they obtain energy from sunlight to make the organic compounds to build or repare the organism
Photosynthesis
Are plants autotrophic or heterotrophic?
Autotrophic
Which ways can plants reproduce
Asexual or sexual
Simplest plants, do not have specialised cells in specific functions
Thallophytes and cormophytes
Where does carbon dioxide enter the plant through?
Stomata
True or false, in asexual reproduction the offspring contains characteristics of both parents
False - sexual
What group are plants with flowers
Phanerogams
What is the type of plant that does not have true leaves, stems or roots
Where does photosynthesis take place, why does it take place there?
Chloroplasts
Because they contain chlorophyll - captures the solar energy
Where are the sexual organs and gamets found on a plant?
The flower
What are the two structures of the pteridophytes life cycle?
Sporophyte
Gametophyte
Name the parts of the cormophytes
Leaves, underside, upper surface, stomata, stem, root
Explain the two types of tropisms
Positive - growth towards the stimulus
Negative - growth away from stimulus
Where is the embryo contained
The seed
How do liverworts reproduce
Propagules - fragments that detached from the plant and from which a new organism grows
Name and explain the two types of conductive vessels
Tracheids and vessel elements - water and xylem sap from roots to leaves
Sieve elemenets - transport products made in photosynthesis (phloem sap) from leaves to every part of the plant
Explain nastic movements
Quick, temporary responses
Seismonasty - stimulus physical contact
Photonasty - stimulus light
Explain two types of asexual reproduction
Bulbs
Tubers
Rhizomes
Explain gymnosperms and angiosperms
G - seed not protected by fruit, female flower ovules are not enclosed
A - flower formed by 4 fundamental pieces, ovary becomes a fruit
