Describe the conditions on Earth that is thought to have favored the evolution of seed plants? What, in your own words, is a seed and how is it different from a spore?
Homework Answers
Evolution of seeds helped plants in reproducing independently of
water for example in lush palms on tropical shorelines , pollen
grains are the male gametophyte which help in dispersal of gametes
at varying distance. While travelling from one plant to another the
whole structure is protected from desiccating without any
dependence on water.
seed is a part of flowering plant to be more precise
reproductive plant which is capable of developing into another
plant of same species.
Difference between seed and spore
1. Survival rate : seeds have higher survival ratio than spores
in plants .
2. Cellularity: Seeds are multicellular where as spores
are unicellular
3. location : seeds are located in the flower and spores are located beneath the leaves of non flowering plants

1. Describe the broad evolution of plants in the plant kingdom (in terms of phylogeny, reproduction, alternation of generations, leaf modifications, and vascularity) 2. Compare and contrast microsporogenesis and microgametogenesis in Pinus and angiosperms). You must use, but are not limited to, the following terms: anther, microsporangia, generative cell, microsporocytes, megasporocyte microspores, pollen sacs, pollen grain, sperm, tube cell, 3. Compare and contrast megasporogenesis and megagametogenesis in...

Complete the following sentences to describe how seed germination can be adapted to environmental conditions. rainfall For a seed to germinate, the embryo will need eaten water and soil However, some seeds also require specific to germinate water and oxygen to open and For example, some pines require release seeds promote Other plants require embryo growth to remove chemicals that cones inhibit or regurgitated to stimulate Some seeds even require being germination stimuli fire dormancy water stimulate Reset

Describe (in words), the life cycle of an Angiosperm starting with a seed that is germinating right now, following that seedling though its life until it produces a seed of its own that will complete one full generation. Be sure to explain the steps involved in this plant’s life cycle related to its alternation of generations. Describe the reproductive structures produced along the way, using proper terminology that we have repeatedly discussed in the context of plant life cycles. Be...

"Describe the 5 major TRENDS in the evolution of land plants; from Bryophytes to Gymnosperms/Angiosperms, AND explain how these trends contribute to success."I am answering questions for my college biology class (second semester of Biology for science majors). We are doing our Plant Diversity II lab. These evolutionary trends are DIFFERENT from the five uniquely derived traits of land plants according to my lab teacher, which based on what I think I know are: 1. Alternation of generations 2. multicellular,...

Plant Chemical Adaptations Physical adaptations are one way plants have become well-adapted to specific environmental conditions. For example, cacti have spines in place of leaves to prevent water loss in the arid conditions of the desert, and deciduous trees lose their leaves in the fall to survive cold weather conditions over the winter. Chemical adaptations are another means for plant protection. Many plants produce toxic or noxious compounds to protect themselves from insects or animals that would eat them, to...
