Systems, methods and apparatuses for processing plant embryos

A pick-and-place method for plant embryos, comprising:

• a) flowing a suspension of singulated plant embryos into a tray while moving the tray;
• b) moving the tray;
• c) while moving the tray, identifying a target plant embryo amongst the plant embryos in the suspension in the tray using an identification system proximate the tray;
• d) after step c) and while moving the tray, picking the target plant embryo out of the suspension in the tray using a robotic arm proximate the tray and in communication with the identification system, the robotic arm actuatable to pick the target plant embryo out of the suspension in the tray while the tray is moving;
• and
• after step d), the robotic arm depositing the target plant embryo at a target location,
• wherein the moving the tray comprises rotating the tray and wherein the tray comprises a base surface and central axis that is perpendicular to the base surface, and the tray is movable by rotation about the central axis, wherein the tray further comprises an outer rim extending upwardly from the base surface and around a periphery of the base surface, and an inner rim extending upwardly from the base surface, whereby the base surface is annular and extends between the inner rim and the outer rim, and the outer rim is taller than the inner rim, and the inner rim defines a drain of the tray.
