Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification.

Photosynthesis - A Survival Guide for Teachers Photosynthesis is one of the fundamental processes on our planet. It’s worth a moment’s reflection… There would be no biology without photosynthesis by plants and algae. These amazing organisms are capable of capturing the energy of sunlight and fixing it in the form of potential chemical energy in organic compounds. They're literally capturing energy from outer space, and we're entirely dependent on them for every breath we take.

Diversity "Diversity is not about how we differ. Diversity is about embracing one another's uniqueness." - Ola Joseph It's Plantin' Time! One of the most anticipated science units in my classroom is our study of life cycles. We spend most of our fourth quarter studying the life cycles of plants, butterflies, frogs, and mealworms. It's one of my most favorite times of the year and one that my kiddos really look forward to!
Eukaryote Eukaryotes can reproduce both asexually through mitosis and sexually through meiosis and gamete fusion. In mitosis, one cell divides to produce two genetically identical cells. In meiosis, DNA replication is followed by two rounds of cell division to produce four daughter cells each with half the number of chromosomes as the original parent cell (haploid cells). These act as sex cells (gametes – each gamete has just one complement of chromosomes, each a unique mix of the corresponding pair of parental chromosomes) resulting from genetic recombination during meiosis.
