Animal Reproduction:

Development in Sea Urchin (Invertebrates) –  view links to videoclips below

• External Fertilization in sea urchins
• How to induce gamete release from sea urchins
• Fertilization in sanddollar eggs (also an Echinoderm)
• Sea urchin egg with sperm, fertilization and development (various short videos)
• Sea urchin gastrulation
• Whole view of fertilization and development in the sea biscuit (also an Echinoderm) -excellent!

Basic Embryonic Development and key terms: note fertilized egg, cleavage, morula, blastula, gastrula, neural tube and gut formation.

Vertebrate Embryonic Development videoclip (1:09) – good for these key terms

Vertebrate Embryonic Cleavage Comparison Chart:

 Frog Deveopment

Early development through hatching tadpoles

 

Medaka and/or Zebrafish Development 

Background info on development in fish

Fish-videoclips

• Zebrafish early development (a few short videos)
• Development until hatching – The “dancing” Zebrafish

 

Life of Insects – Attenborough: Life in the Undergrowth– videoclip (8:11)

Neat clip showing dispersal strategies of stick insects and blister beetles – both “use” other types of insects to increase survivorship of the next generation.

Complete Metamorphosis

Short video showing complete metamorphosis in Honey bees (1:08)

 

Incomplete Metamorphosis 

 

 

Plant Reproduction

Alternation of Generations – remember this from BIO 181?

Alternation of Generation -animation in ferns and angiosperms

Life Cycle of a Flowering Plant (5:03) -more detailed than above.

Pollination and Fertilization -videoclip

Floral Structures

 

Embryo Development in Plants – (Capsella Embryo Development)

 

Arabidopsis – seed germination:

 

Monocotyledon and Dicotyledon Seed Structure and Germination – How are they alike? How are they different?

 

 

Vegetative (Asexual) Plant Reproduction – many plants are propagated asexually

• . ??insert picture from lab counter? find old pics
• Short video showing a few examples
• The Science of Vegetative Plant Propagation (30:01, long but good)

 

Apical Meristems and Primary Growth – good diagrams of primary meristems and primary tissues.

• Can you find the follow primary tissues below: apical meristem, protoderm, procambium, leaf primordia, bud primordia, ground meristem?  What tissues do each of these give rise to?

 

Plants in Motion – time lapse photography showing a variety of ways in which plants move. Cool clips to check out:

• Photomorphogenesis – Sunflower
• Tropism – Gravitropism Coleus and Sunflower. Also Sunflower Solar Tracking
• Nastic Movements – Venus flytrap, Sensitive Plant, Morning Glory, Tulip Stem
• Circadian Responses – Bean Leaf and Pulsing Pumpkins
• Flowers – any of these
