- micropyle
- the small pore in the seed that allows water absorbtion
- vascular plants
- plants that have vascular tissue
- vascular tissue
- an internal system of tubes that transport substances within the plant, it also helps with support
- angiosperm
- a plant that produces seeds that are inclosed in a fruit
- ovule
- female gamete
- seta
- the long filament that has a sporangia attached to the end
- stomata
- tiny openings or pores on the underside of a leaf
- Intermediate plants
- simple vascular tissue, mid size, use spores
- embryo
- the young plant that develops from the zygote
- seed
- structures that contain young plants inside a protective covering
- woody stem
- hard stems, maple trees have this type of stem
- zygote
- fertilized egg
- stigma
- tip of pistil
- auxin
- a hormone that speeds up the rate which a plant's cells grow
- anther
- top part of stamen often yellow
- germination
- the early growth stage of the embryo
- What is a stems function?
- it carries substances from the roots to the leaves and hold the plant up, it also holds the leaves up for photosyntheis
- fibrous root
- branching roots like in a tree
- embryo
- the young plant that develops from the zygote
- petals
- the leaflike structures which are used to attract insects
- hilum
- the scar on a seed coat at the location where it was attached to the plants stalk during development
- cuticle
- waxy water proof layer that covers the leaves of most plants
- tropism
- a plant's growth response toward (positive) or away from (negative)
- rhizoids
- small root-like structures that anchor moss
- sporophyte
- the stage in the life cycle of the plant in which the plant produces spores
- hypocotyl
- forms the stem and the roots
- pistils
- female reproductive parts
- pollination
- when grains of pollen fall on the stigma
- annual rings
- rings found in the trunk of a tree caused by the xylems growing pattern; one is formed each year
- types of roots
- two types: fibrous and taproots
- fruit
- the structure that the ovary eventually changes into
- characteristics of seed plants
- have vascular tissue and use seeds to reproduce
- spores
- a tiny cell that is able to grow into a new organism
- sepals
- protect the developing flower (bud)
- seed coat
- the protective covering of a seed
- Complex Plants
- flower/seeds/pollen, trees/shrubs, Vascular tissue, tall
- epicotyl
- forms the first leaves of the developing embryo
- xylem
- the vascular tissue that water and nutrients move through
- bog
- a very acidic wetland
- Simple plants
- non-vascular, very short,produce by spores, don't need soil, wet enviroments
- seed parts
- embryo, stored food, and a seed coat
- mosses
- low growing bryophytes
- What is a roots function?
- anchor a plant in the ground and absorb water and nutrients from the soil
- gametophyte
- the stage in the life cycle of the plant in which the plant produces sex cells or gametes
- herbacious stems
- soft stems, dandelions have this type of stem
- flower
- the reproductive structure for an angiosperm
- tissues
- groups of similar cells that perform specific functions within the organism
- nonvascular plants
- low growing plants that do not contain vascular tissue
- root cap
- a hard tip that protects the root from injury
- fertilization
- when the pollen tube is formed and sperm goes down the tude and fertilizes an egg
- Characteristics of seedless vascular plants
- have vascular tissue and use spores to reproduce
- Plant Characteristics
- they are all multicellular, autotrophs that are also eukaryotes
- peat
- layers of dead moss in a bog that are compress
- transpiration
- the process in which water evaporates from a plants leaves
- tap root
- on thick main root a carrot is this type of root
- style
- the thin stalk that holds up the stigma
- stamens
- male reproductive parts
- plumule
- the shoot of an embryo
- How many types of angiosperms are there?
- there are two types monocot and dicot
- ovary
- the protective vessel where the seed develops
- dicot
- an angiosperm with two cotyledons
- bryophyte
- simple plants ex: mosses, liverworts and hornworts
- filament
- the thin stalk that holds up the anther
- What are the three important stimuli to which plants respond?
- touch, light and gravity
- What is the leaves purpose in a plant?
- they capture the suns energy and carry out the food making process of photosynthesis
- radicle
- the very tip of the root
- phloem
- the vascular tissue that food moves through
- What do plants need to survive on land?
- be able to obtain water and other materials, retain water, transport materials inside themself, support their bodies,reproduce succesfully
- sporangia
- the tiny structures in which spores are produced
- hormone
- a chemical that affects how the plant grows and develops
- cotyledons
- the seed leave in which food is stored
- monocot
- an angiosperm with only one cotyledon
- gametes
- sperm and egg cells
- angiosperm characterisitics
- they produce flowers and fruits
