Plant Responses to Abiotic Environment

Plant Responses to Abiotic Environment. Biological orientation of plants. Tropisms: when growth toward stimulus it is positive and vice versa. Taxes: occur in algae which swim with flagella and swim toward light. Nastic responses: turgor response to diffuse stimulus. Not fully understood.
