What is morphogenesis?
Formation of the structure of an organism or part; differentiation and growth of tissues and organs during development
In what 4 ways are seeds adaptive?
1)Seed can remain dormant in unfavorable conditions

2)Maximum protection is given to young plant during vulnerable stages

3)Stored food permits young plant to develop prior to photosynthesis

4)Facilitates migration of genotypes to new habitats
What are the 4 main kinds of fruit dispersal?


3)Animal coats

4)Animal digestive tracts
What is germination?
The resumption of growth and development by a spore or seed
What is a scutelum?
The modified cotelydon in cereal grains
Water moves through what areas of the plant?
Spaces between cell protoplasts

Which 3 macronutrients constitute 94% of the plant's dry weight?
Which 6 macronutrients constitute 1% of the plant's dry weight?
C HOPK'NS CaFé is Mighty good
How is a hydroponic culture used to identify nutritional requirements of plants?
1)a seedling is grown in a complete nutrient solution

2)the seedling is transplanted to a solution that lacks 1 suspected essential nutrient

3)the growth of the seedling is observed for the prescence of abnormal symptoms

4)if the seedling's growth is normals, nutrient may not be essential but, if the growth is abnormal, nutrient is essential

What 3 kinds of plants are Bryophytes?


What do gametophytes of mosses typically consist of?
Small leaf-like structures arranged spirally or alternately around a stem-like axis, anchored to substrate by rhizoids
What is the archegonia?
A female sex organ occurring in mosses, ferns, and most gymnosperms
