Arrested development Plants procreate through a double fertilization. They don’t get twins, only one of the two sperm cells fertilizes an egg cell. The second sperm cell is needed for the fertilization of the central cell. To form the endosperm, tissue that supports the developing embryo in its growth and germination. Giving the endosperm anContinue reading “Arrested development”

Keeping the balance when submerged
Keeping the balance when submerged Plants, just like animals and humans need oxygen to survive. Normally this is no problem. As a by-product of photosynthesis, oxygen is freely available. But by flooding a plant is under water, no photosynthesis can take place resulting in a lack of oxygen. To survive such a submergence, plants switchContinue reading “Keeping the balance when submerged”
Balans houden bij onderdompeling
Balans houden bij onderdompeling Planten hebben net als dieren en mensen zuurstof nodig om te overleven. Normaal gesproken geen probleem. Als bij product van fotosynthese is zuurstof ruim aanwezig. Maar is er een overstroming en staat de plant onderwater, kan er geen fotosynthese plaats vinden en is er een tekort aan zuurstof. Om zo’n onderdompelingContinue reading “Balans houden bij onderdompeling”
Working together
Working together The first thing a seedling does, after its germination, is growing upwards. To get above the ground into the sunlight. A seedling gets there not so much through cell division, but through stretching itself. Researchers know that this is regulated by the plant hormones auxin and brassinosteroid. But how these two growth-managers workContinue reading “Working together”
